ACCELERATION-BASED MOTION TOLERANCE AND PREDICTIVE CODING

摘要

PROBLEM TO BE SOLVED: To provide a method of predicting the location of a region of interest within an image of a scannable object.SOLUTION: The method comprises: providing a scanner having a processor and an image sensor; sensing in a viewing direction toward a scannable object, with an imaging plane being perpendicular to the viewing direction; capturing an image of the scannable object with the image sensor; sensing motion of the scanner within a motion sensor plane relative to the scannable object, the motion sensor plane being parallel to the imaging plane; outputting a velocity and a movement direction corresponding to the velocity; locating a region of interest in the captured image in response to the velocity and the movement direction; and scanning the captured image beginning with the region of interest.SELECTED DRAWING: Figure 2
